Hello All.
My first post here. Not new to lasers in general, in fact I own a company that produces laser cutting and engraving systems. Lasers have been a hobby since I was a kid.
I recently decided to get back into Laser Displays as a hobby, and I'm currently building an RGB projector using Lasers from DHOM (Ultralasers), DHOM-I-445-600 600mw 445nm Blue, and DHOM-M-532-300 300mw 532nm Green.
I sent an e-mail to Shawn at Ultralasers asking if these two units had differential inputs but have received no reply...
I am using an FB3 DAC with Quickshow, and DT-40 Pro scanners.
The green laser is currently connected for testing and all seems well, but was just curious if I really need to put an op-amp (differential to single ended converter) between the differential output from Pangolin's FB3 and the inputs to the laser driver... Have not tested the blue laser yet, but that will happen this weekend.
For Red, I have a 300mw 640nm on order from David at LasershowParts, and I know this unit is a LaserWave module.

Also not sure about the LaserWave and whether it will also need a differential comparator circuit as well.
Any advise or info would be greatly appreciated...
Thanks,
Robert
